Is it okay to blit surface with a negative coordinates? Can it cause to crash my game if I keep using negative coordinates? Since they declared SDL_Rect x and y a Sint16 ( If im correct its a signed integer 16 bits ) I think its okay to use negative numbers but I just want to be sure about this.

It's fine.

See this.

Quote:Only the position is used in the dstrect (the width and height are ignored). Blits with negative dstrect coordinates will be clipped properly.
